But they're shit because the people who work for them take all the money. With the cap greed is a much smaller factor and would likely lead to those charities to either get their shit together or shut down

Edit: and you're right in an ideal government charities wouldn't even be necessary because taxes are handling everything a charity would but it will never be perfect and I think giving people the option of where their earned money goes would be a lot less aggravating than being forced to give it to the US government
